This is fic is inspired by an anime and manga. First is the manga Boku no hero academia. I started reading it last year and then I thought of a world where everyone has powers but then I thought that's too broad to be writing about still, I kept imagining scenarios.

Second is the anime my cousin suddenly got obsessed with, Soul Eater. I don't watch or read it for reasons I don't know. I might read it one day… I liked the pairing thing. And I thought, this is it! Pairs! So there we go. I don't take credit in the Meister/Weapon thing.

In this world, everyone is either a Shifter or a Meister. There are four classes, starting from the lowest: Class D, C, B, A, and S. S being the highest.

More notes at end of story, please read them! Thank you!

Time sure was slow.

Levi clicked his tongue as he looked down at his watch for the nth time that night. What was taking them so long? Hadn't they planned this mission for almost a month before they could take action? Levi did not suffer aching knees and all those chilly nights out to observe their target' security pattern just to have this whole mission called out just because they can't click a. Damn. Button.

"Fucking shit, those assholes. Better have a good reason or I'll pummel their asses to the ground." Levi muttered under his breath irately. The explosion was supposed to set off a few minutes ago.

"They might be just finding the right moment to set off the distraction." The spiky blonde on his right whispered as he slid his binoculars off his face, although the way his lips turned down showed even that even he was displeased. Farlan never like it when things didn't go as planned.

"Yeah, bro. You do know that Petra and Eld have good timing." A twintailed redhead piped, shifting slightly to shoot him a grin.

"Stop moving, Isabel. Do you want this mission go to shit?" Levi hissed as he cuffed the blonde on the back of his head. "And you, put your head lower. Your chin shouldn't go higher than the peak of the roof. You only need your sight to look, not your fucking mouth."

"Farlan's been scolded~" Isabel' singsong voice drifted softly to Levi's ear. Both men turned their head towards her with a glare which she returned with a cheeky grin before turning her full attention on the task at hand and raising her binoculars to her greenish eyes.

They were located at the tall building on its far right that gave them a good view of the huge mansion; its wide backyard littered with tall trees parallel to the walls and smaller one, framing the long circular driveway.

Levi sighed. This two could be quite a handful during their idle times but they do know when to stop. The three of them had been friends ever since they met on the underground and proven their trustworthiness to him although his relationship with Farlan was more rocky at first since the guy did trick him once in the black market when he was buying a modified gun but things turned out fine in the end when Farlan, after a year of the said incident, saved a young Isabel from a group of misfits and asked to be in their group with them, bringing with him a couple of useful trinkets.

Levi though knew that Farlan just wanted to be closer to Isabel, the way he'd look at her was painfully obvious but Isabel was a dumbfuck and since Levi himself was just as good at love as he was with cooking—which was shit—Levi just silently cheered the love struck man a good luck and left them by their lonesome.

He believed that things would turn out in the end which it did, thankfully, although he had to endure watching them dance on their tip toes around each other for years and an accident of Isabel almost being kidnapped four years back sealed the two blabbering lovebirds' fate. Perhaps that was why their wavelengths were so matched that Isabel changed from being just a normal class Shifter to an Aberrant.

At first, they weren't really sure as to what class Isabel was, or any of them really, since they were born in the underground city where there was no actual doctor—just wannabe doctors—and the equipments were shit.

Normally, when a baby is born, the doctor would tell them an estimate as to what sort of class the newborn is using an equipment for reading wavelengths, only an estimate though, since a child's wavelength's fluctuating and only steadies when they are at the age of six.

It was mandatory to every registered citizen to get their wavelengths analyzed and give it to the government branch tasked to file such things.

Meisters only had to give them their class but Weapons had it tougher. They had to appear personally and the officer in charge would find a good match to wield them to be able to profile what sort of weapon they were even if they were just a class D shifter.

People who grew up in the underground had no such way of knowing what sort they are unless they fuse with other people. Levi found out he was a Meister when he accidentally fused with another child he helped.

He almost had a heart attack when the kid all of a sudden vanished and in its place was a fork. In his shock and panic, he flung the fork as far away as possible and along with it, the two were forced apart.

They had just taken to calling Isabel a class B Shifter—since bombs could kill singlehandedly even take away countless lives in just one throw—and with Farlan as her Meister, he was also dubbed B class and since they were an Aberrant Pair, it didn't really matter, as long as they were certain that they could win because that was all that mattered in the underground city.

Since there was nothing to do on the underground aside from keeping themselves safe and fed, their time on the underground allowed them to observe what a Pair's class could be and in turn, tell what class of Shifter someone could be.

It was a necessary skill if they wanted to survive and make sure that they would not be defeated.

Their only problem was Levi.

He was too pigheaded and did not want to fuse with anyone since it left a bad feeling on his stomach. So they still could not tell what sort of class Levi belonged in but it was no matter since Levi was strong even by himself.

It was when the police force went to the underground to capture a bunch of strong criminal Pairs that they learned that there was a handy device—a class identifier gun or CIG—that could be used to tell what class a person is along with his type but it was strictly for governmental use, even in the police force, not every branch could use them.

In all of Levi's twenty nine years of living, he'd wasted eight of it with them—seven with Farlan since Levi hated him for a year before the blonde helped Isabel but technicalities be damned—even when they moved above ground they kept close ties.

Their bickering was almost a constant noise in the background and they were the closest to a family he could get. Levi was older than Farlan by a year while Isabel was the youngest falling back three years so it was completely understandable that they were protective of her, Farlan more so.

The raven-haired man found it fascinating how Farlan would hiss like a fucking viper when another Meister would come close to Isabel with the slightest intention of wielding her—in one way or the other—fascinated after they had seen them fuse although they wouldn't know that they were an Aberrant.

There really was no way of knowing if a Pair was an Aberrant or not unless another Meister fuses with the Shifter or the Pair expressly tells that they are one. Levi had told them to keep their status a secret.

"How many minutes do you think we have when the bomb goes off, bro?" The redhead asked patting her butt clean of any dust. Levi appraised her silently.

"Three or four before they get their asses back in gear and another ten for their reinforcement to come if there are." Levi responded.

"That should be more than enough." Farlan added, "And since our last mission wasn't much of a challenge, we hardly needed to use your bombs more than necessary. Gunther and Oluo were more than enough."

"Even if we did, I just need to eat more and they'll be replenished the next time we fuse." Isabel said, pouting.

"You eat more than we do anyway." Farlan whispered but from the indignant squeak that came soon after, his Shifter heard.

"Why you! I'll have you know that all Weapons are like that! How could you!" Isabel retaliated in a shout-whisper. "I'll never let you fuse with me again!"

"Yeah, yeah. Why must you always say that?" Farlan groaned, "And besides, not all Shifters have the same side effect as you. Just admit it, you're a glutton!"

Only Shifters had Side Effects, this is what they need most to replenish both weapon and gear. It could be in the form of eating or drinking something specific or just eating or drinking in general or both; while it is a general rule that all Shifters—those that fuses with their Meisters in a daily basis—should have at least ten hours of sleep.

"Stop it, you two." Levi cut in with a harsh tone; he did not like having people have a shouting contest especially when he was in between them. "Act your age, for fuck' sake. We're undergoing an operation here or do you want to starve again like we did back in the underground?"

Although starving was not a problem to them anymore for years now, still it did give its intended effect; the two shut their traps and placated themselves with glaring at each other, with Isabel whacking Farlan with her binoculars once.

Their mission was simple in terms of what they'd have to do but the site of operation was not,— and he quote "To take back my baby and my necklace from them and cause as much damage as they could on their property while you're at it and Do. Not. Harm. My. Baby." Followed by a good imitation of Levi's death glare that had his team's spine shiver in fright—the woman had handed them a picture of both jewel and babe and the picture of the mansion which they recognized immediately. It was that mansion owned by that one man connected in making drugs.

In short, this whole mission was just a personal vendetta and they was still hang up about exactly how they would find the necklace in a huge ass mansion.

Still, he applauded the woman who had even talked to them face to face herself when all of their clients used other people or, most commonly, called their business number—Yes, their team had gone so far up that they even had their own office down underground which was being manned by a hired personnel and somewhere in the city—just to give them their mission.

It was then that Levi finally understood the meaning of the saying 'Hell hath no fury like a woman scorned.' Although she was not so merciless that, when Petra had informed her that they do not kill people, she told them as long as they suffered, any way was fine. It was a drug lord's home and that meant that it would be heavily guarded but they still liked a challenge so they accepted.

Levi was not one to pry into other people's business but this woman's fearlessness of having her real identity known on the underground deserved applause. Levi had already gathered that that baby was her child and she wanted him back although he was not as sure for the necklace.

They still couldn't turn on their communication device since they might be detected although Levi did receive a message that they might be later than the expected time of detonation.

He settled his night vision binoculars on his eyes—just one of the things that they had acquired on their past operation on a storehouse of a well-known brand of stealth equipments a couple months ago and was Levi so glad that he had come across a blueprint of their storehouse, although it did cost quite the fortune as well and a pretty high gamble since he wasn't yet acquainted with the information broker.

Not to mention, getting inside a storehouse of a stealth company would be quite the task but they persevered. Planned for three whole months and watched them like a hawk. Even though they had all those high gadgets, it would seem that that company had been lacking on the physical side of the fight, which Levi's team was known for.

The company had hired Pairs alright, but Levi could tell that they were on the mere class of B and a couple of class A.

Levi may be a Meister with no weapon but he was just as strong as a Pair of class A could ever be and he'd handled the class A Pairs like they were mere class B's although the same could not be said to his team as they struggled to fight. They had gotten serious injuries even Levi had cuts and bruises.

It had ended in a total success though, if the high tech gadgets that they were now using were of any indication and needless to say, they had caused quite the misfortune for said company since they had been greedy with what they could take and load into their worn but trusty trucks and it just so happened that the storehouse was fully stocked then since it was due for exportation. Well, talk about good luck.

The bounty on their heads went up for that one operation but who cares. A bounty was a bounty no matter how high, they're screwed anyway.

And they were still not on the red list of people that had to be taken into custody since they haven't killed anyone, just wreaked havoc and disrupted their target or city's otherwise peaceful everyday life.

Really, Rivaille' Squad were not that far from a band of thugs, they were just more high-end and with an Aberrant Pair and the Strongest Meister to ever walk the earth, they had more fame than usual…

It was their biggest and most successful as of yet in terms of personal operations.

"Speaking of, we need more bombs." Levi said idly as he glanced at the glowing numbers of his watch. Just a few seconds has passed.

"Yup. We used most of them on the past mission and forgot to stock up. We're also running low on timer bombs and smoke bombs… even though you have me…" The redhead informed him with a bitter voice.

Isabel had quite the love on blowing things up, although Levi knew that it had everything to do with her as a Shifter, it was still a wonder why she was here with him in the first place when she could have been with Petra and Eld, cackling like a sadistic bitch back on the dummy site as she blew things up…

'On second thought. No. This is better. She'd probably go overboard with pushing the damn buttons if she were there even if it would attract more attention. It would have been too flashy, not to mention we need her here for a reason.'

Levi wondered if they could make that stealth company go bankrupt. A sardonic grin stretched across his thin lips. Perhaps it was time to get back on that company…

"Nah. Not worth the shit. They'd probably hired Aberrants since then and tightened their loose asses."

The other two turned to look at him curiously but a dark vehicle passing on the street below them caught their attention.

Frowning, Levi adjusted his binoculars for better view as he followed the tail of the car as the electronic gates opened up to allow them entry; it had no plate number and was tinted as dark as Satan's ass so he couldn't see inside.

There were lesser the men he saw during his surveillance mission on standby today—just an even number of eight people which meant that they were all Pairs—and it had proven the veracity of their information broker which was just right since they did pay quite the sum of money just to get the information they needed to break inside the mansion.

Levi had also seen three luxury cars pass by in the past thirty minutes, right on the dot. The last one carried the master and mistress of the house as the information had stated and they had verified that as well when they watched them get inside the car.

But this. This van was not stated.

"I'm gonna fucking kill that bastard. If we finish this operation I'm gonna hunt his stinky ass down." Farlan was also silently fuming beside him.

Levi may have been quite familiar with changes in plans or having something unexpected happening resulting in impromptu actions but that man had told them that he was absolutely positive about his information that he charged them more than was necessary and all that with no blueprint although he had provided them with the types of Pairs that they could possibly have battle with that was why Levi allowed Petra and Eld to fight them alone and had to be stuck on the more tamer part…

'Still, that greedy fucker. This better not be more Pairs or those masters.'

Men in black exited the vehicle as soon as it had stopped and without wasting any second they took out what looked like a large box…

'No wait, is that a coffin?' Levi scooted closer on the edge, chin getting past the peak of the roof as his binoculars stuck on his eyes. He watched them closely. 'But then again, coffins don't rattle…'

"Holy shit, is that a vampire?" Levi heard Farlan mutter on his side. He was secretly, or in this case not so secretly, a fan at heart. No matter how much of a serious assfuck he was. Levi could almost feel the excitement rolling off him in waves. "…Perhaps a zombie… Or a… A cyborg…"

"Oh please. As if they're true, you fantastical bastard." Before they could bicker more, Levi hushed them up with a quick click of his tongue.

They watched them until they disappeared past the heavy-looking steel back door that slid open with the click of a password, all the while thinking of what could be in there.

'A human of course, but what do they need them for…' Somehow Levi felt a bad feeling settle on his stomach. 'At least only two people stayed behind. They are probably a high level Pair.'

They saw the same men get out; they talked to a man standing guard nearby before getting back inside the van and driving off. Two of those men were left behind so most probably they were inside guarding whatever was inside the box.

This is my very first fanfic and my first time writing anything aside from school essays or whatever the hell they feel like making us write, ugh. School.

So if you could help me improve myself and this story, I would be very thankful since I have a lot of different story plotlines brewing in my mind for this ship and my other fave ship. Critics are welcomed just don't be rude, I have a weak heart. Hahaha…

In another note, if anyone had a name that I could call a Pair (the fused pair) then I would gladly take them into consideration since I suck at giving names, or calling anything in general. I gave my dog the name Gon even though my beloved Dog is white as snow… and Yes, that's Gon from HxH. I'm so lame…
